Assistant coach Frank Hamblen says the Lakers spent too much time dribbling instead of passing in Game 2 of the NBA Finals against Boston and need more efficiency on offense.

Reporting from Boston -- Lakers assistant coach Frank Hamblen stood outside his team's coaches' office Sunday night after Game 2 of the NBA Finals, his game notes in a folder tucked under his arm, as player after player solemnly eased his way out of a quiet locker room.

The Lakers had just lost, 103-94, to the Celtics, and in the process lost home-court advantage as the best-of-seven series that is knotted at 1-1 shifted to Boston for Games 3, 4 and 5.

Hamblen, in charge of putting the Lakers' game plan together against the Celtics, was emphatic when he described what the Finals now have become.

"We've got a serious series now," Hamblen said, chuckling.

And what if the Lakers and their fans didn't know that already?

"Well, they know it now," Hamblen said, smiling.

When Hamblen turned serious, he pointed out how the Lakers refused to move the ball through the "air" in the Game 2 loss, which just made Boston's defense that much better.

That allowed the Celtics to load up on defense and limit the Lakers to 40.8% shooting and 22.7% (five for22) from three-point range.

"You have to give them credit," Hamblen said. "They got their split. They accomplished what they wanted."

Hamblen said the Lakers would watch film Monday before they boarded their flight for Boston.

He'll have several things to preach to the Lakers.

Better ball movement.

"We have to swing the basketball by the pass and not the dribble," Hamblen said.

Pound the ball inside to Pau Gasol and Andrew Bynum.

Gasol and Bynum were too much for the Celtics, combining for 46 points on 13-for-20 shooting. But the Lakers went away from the big men in the fourth quarter. Gasol and Bynum combined for only five points and got off a combined three shots in the final quarter.
